Abstract: In an exhaust gas cleaning apparatus (30) in which a before and after differential pressure (?P) of a filter (32) used to trap particulates is detected for regeneration of the filter (32), a time at which, during filter regeneration, the temperature of the outlet section of the filter (32) falls below the temperature of the inlet section thereof (?T>M), using a first temperature sensor (36) and a second temperature sensor (37), is determined as being the timing of the completion of the regeneration of the filter (32). The value of the before and after differential pressure (?P) at the time of this regeneration completion is used to estimate the quantity of residual ash in the filter (32), and when this estimated residual ash quantity is the same as, or greater than, a prescribed value (PX), a replacement warning signal (K3) is output urging replacement of the filter (32).

Abstract: A method and system for detecting and predicting air filter condition for an air handling system operates by determining a system resistance to air flow. The system resistance is utilized to determine a detection statistic indicative of current filter condition and to predict remaining life of the air filter. The system resistance is determined using models that approximate the expected operation of the air handling system. The approximation is then compared to actual values to obtain a difference. Once the difference between the approximated value exceeds a threshold value, an alarm is initiated that is indicative of system resistance. The remaining air filter life is then determined by using historically gathered data, or by using a known degradation rate of the air filter. Once the remaining life of the air filter is estimated, replacement can be scheduled that would coincide with other maintenance.
